Tubular chassis builder

[Speedfreak]

As others have asked. What are you trying to achieve, prevent or are worried about?

For daily driving, you should just do a cage in a normal chassis car, with swingouts. There is no need to do all you are talking about, if corrosion is your worry. Everything can be fixed or replaced for cheaper than what you are proposing.

None of this will "pay off" in any sense of the meanings, so not sure what you mean by that comment above.

Back to the original question, what do you think all this will achieve? What are you trying to achieve? Answering this clearly will help us all give you sound advice.
